The National Energy System Operator has introduced a fast-tracked, strategic pipeline to prioritise ready projects and accelerate the UK’s journey towards its 2030 decarbonisation goals, potentially unlocking £40 billion annually in clean investment.
The National Energy System Operator (NESO) has published a defined, fast‑tracked pipeline of deliverable energy projects designed to accelerate progress towards the UK government’s Clean Power by 2030 objective and unblock investment in decarbonisation.
According to the original report from NESO, the new pipeline identifies 283 GW of generation and storage capacity and 99 GW of transmission‑connected demand that will be prioritised for connection to Great Britain’s electricity networks. The reform moves the system away from a first‑come, first‑served queue , which swelled to more than 700 GW in recent years , towards a model that prioritises project readiness, planning certainty and strategic alignment with national energy goals. The operator says the change could unlock roughly £40 billion of clean investment each year.
Industry and government sources say the overhaul was developed in close collaboration with network operators, investors, Ofgem and ministers to eliminate non‑viable “zombie” projects and concentrate capacity on schemes likely to deliver by 2030 and beyond. NESO has signalled that the first set of protected offers , aimed at projects targeting connection in 2026–27 , will be issued with confirmed connection dates from December and into the new year, with remaining offers expected by Q3 2026. From late 2026, projects may reapply to enter the process provided they can demonstrate readiness and strategic fit with the Clean Power Action Plan.
NESO chief operating officer Kayte O’Neill said in a statement: “Transforming the grid connections process is a vital first step in unlocking the capacity needs for a secure, affordable energy transition. These changes will cut grid bottlenecks by prioritising ready‑to‑build projects, giving certainty about when and where they can connect and unlocking billions in clean energy investment.” The operator emphasised that the reforms build on an evidence submission window and a temporary pause on new applications earlier in 2025 intended to allow the system to be redesigned.
The reprioritisation will affect a broad mix of technologies. Reuters reporting of NESO’s review process indicates that of nearly 3,000 applications assessed, around 132 GW were identified as essential for the 2030 pathway, with additional capacity earmarked to 2035 and substantial allocation for high‑demand users such as data centres. Over 300 GW of less viable proposals were excluded from the protected pipeline. NESO and government materials highlight that a clearer, staged connections timetable should help networks plan where reinforcement is needed as electricity demand rises through to 2050.
The connections reform dovetails with other public‑sector initiatives to scale renewables and storage. Great British Energy’s five‑year plan, backed by public funding and private capital commitments, targets rapid delivery of generation and storage capacity to support regional supply chains and jobs , reinforcing the need for a streamlined route to grid access if those projects are to reach financial close and construction on schedule.
For industrial decarbonisation stakeholders, the changes deliver two immediate implications. First, greater certainty over connection timing will improve project bankability and allow developers, investors and industrial off‑takers to align procurement and offtake contracts to realistic network timetables. Second, the shift to a readiness‑and‑strategy‑based allocation means project sponsors must tighten planning, land rights and consenting evidence now or risk exclusion from the protected pipeline , with the next opportunities to enter the process set against demonstrable delivery capability.
NESO and government documents note that final arrangements remain subject to regulatory decisions and future legislative steps to lock reforms into the statutory framework. Industry participants should therefore treat the new pipeline as a materially more certain planning signal than the old queue, but monitor Ofgem and NESO decisions closely as offers are issued and regional network needs are confirmed.

- https://www.reuters.com/sustainability/boards-policy-regulation/britain-overhauls-power-grid-connections-root-out-zombie-projects-2025-12-08/ – Britain’s National Energy System Operator (NESO) has announced a significant overhaul of the electricity grid connection process to expedite viable power generation and storage projects and eliminate so-called ‘zombie’ projects that have been delaying progress. This reform is crucial for meeting the country’s goal of largely decarbonising its power sector by 2030, which requires a substantial increase in renewable energy sources such as wind and solar. The old first-come, first-served system caused a backlog of over 700 GW of projects—far beyond the necessary 2030 requirements. The new system will fast-track projects that have planning permissions, land rights, and align with national energy strategies. Of the nearly 3,000 applications reviewed, 132 GW are deemed essential for the 2030 clean energy target, with another 151 GW needed by 2035, and 99 GW allocated for high-demand sectors like data centres. Over 300 GW of less viable projects will be dropped. This reform, backed by the UK government and Energy Secretary Ed Miliband, follows months of collaboration among NESO, industry stakeholders, and regulator Ofgem.
- https://www.reuters.com/sustainability/climate-energy/britains-great-british-energy-unveils-plan-boost-renewable-power-by-2030-2025-12-04/ – Great British Energy (GBE), the UK’s state-owned energy firm, has announced a strategic five-year plan to significantly accelerate the country’s renewable energy development in a bid to help decarbonize the power sector by 2030. The company’s goal is to deliver 15 gigawatts of clean energy generation and storage—enough to supply power to about 10 million homes—by combining its own investments with £15 billion in private finance. Supported by an £8.3 billion government pledge, GBE will focus on local community energy projects, onshore energy, and offshore wind development. The initiative will also act as both a developer and equity investor, with profits reinvested into expanding renewable capacity. By 2030, GBE expects to be income-generating and on track to overall profitability. The plan will support over 10,000 jobs, particularly in regions that have traditionally depended on oil and gas, and aims to back more than 1,000 community-driven energy initiatives.
- https://www.neso.energy/news/unveiling-new-project-pipeline-deliver-clean-power-2030 – The National Energy System Operator (NESO) has confirmed a new pipeline of deliverable, shovel-ready energy projects that will be prioritised for connection to the electricity networks, unlocking £40 billion in clean investment annually and driving progress towards the government’s Clean Power by 2030 target. NESO has worked closely with government, investors, networks, Ofgem, and the wider energy industry on a major overhaul of the connections process, after the old queue for grid access grew tenfold in five years, reaching over 700 GW, around four times Great Britain’s projected need by 2030. From today, thousands of projects, from wind and solar farms to battery storage and hydrogen will learn whether they are part of the 283 GW of generation and storage capacity and 99 GW of transmission-connected demand. This defined set of deliverable projects will form a new pipeline as the system moves from a first-come, first-served model to one that prioritises projects ready to meet Great Britain’s energy and economic needs.
- https://www.reuters.com/world/uk/uk-grid-operator-pauses-connection-applications-allow-reform-2025-01-15/ – Britain’s National Energy System Operator (NESO) announced a temporary suspension of new grid connection applications starting January 29, 2025, to focus on implementing reforms aimed at improving the electricity network. This pause follows recommendations by energy regulator Ofgem in November 2024, which proposed new regulations to address the growing backlog of renewable energy projects awaiting grid access and to align energy technologies with future needs. NESO received over 1,700 applications in 2023/24, resulting in a queue that already exceeds the projected needs for 2030 and even 2050. The volume has made it impractical to pursue reforms alongside the current process. However, demand projects directly connecting to the national electricity transmission network, typically large-scale industrial and commercial users, will not be affected by this pause. NESO aims to use this period to work with network partners to implement new processes crucial for delivering clean power targets.
- https://www.gov.uk/government/publications/clean-power-2030-action-plan/clean-power-2030-action-plan-a-new-era-of-clean-electricity-connections-reform-annex – This annex provides a detailed breakdown of the Clean Power Action Plan pathway and capacity ranges, for the purposes of aligning the NESO (National Energy System Operator)-led process of connection reform with 2030 Clean Power (subject to NESO (National Energy System Operator)’s final proposals being approved by Ofgem (Office of Gas and Electricity Markets)). This includes GB (Great Britain)-level capacity ranges, informed by NESO (National Energy System Operator)’s 2030 advice and in line with the government’s 2030 pathway for most generation technologies, and regional breakdowns for onshore wind (ONW (onshore wind)), solar, and batteries. We have also set out technology capacity ranges to 2035 to provide a 10-year horizon for connection offers. These are mainly derived from NESO (National Energy System Operator)’s net zero-aligned 2035 Future Energy Scenarios (FES (Future Energy Scenarios)) 2024, with a bespoke approach for onshore wind and unabated gas (see the note on bespoke approaches). NESO (National Energy System Operator) has now consulted on its proposals for a strategically aligned process and reform of the existing connections queue and expects to submit final recommendations to Ofgem (Office of Gas and Electricity Markets) by the end of 2024, for a decision by the end of Q1 (quarter 1) 2025. The government strongly supports connections reform and plans to introduce legislation, when parliamentary time allows, to ensure connections reform aligns with strategic energy and network plans and supports delivery of Clean Power by 2030. This should provide certainty to all parties on the direction of travel for connections.
- https://www.neso.energy/news/clean-energy-projects-be-prioritised-grid-connections-reform-evidence-window-opens – Today, 8 July, marks the opening of our Connections Reform evidence submission window, the next step in radically transforming the way projects connect to Britain’s electricity network. Until 23:59 on 29 July, energy generation and demand projects with an existing connections agreement can begin submitting evidence to showcase their readiness and strategic alignment with the UK’s energy goals. Although the window is open for three weeks, we urge customers to submit evidence as early as possible. Connections reform will open the way for clean power projects like new wind and solar farms to connect to the power grid, ending a growing gridlock. It is an instrumental step in achieving the government’s Clean Power 2030 ambition, which will help unlock up to £40 billion a year of private investment in clean homegrown power, bolstering economic growth.
